The thermometer it right ontop of the eggs, both thermometers say right about 99.5 degrees f . I filled the pan at the bottom with water like the instructions said. Not sure on the EXACT humidity though.
The best one is from Rush Lane Poultry. He goes through each step in about four videos. My works great. I have hatched about 200 quail and 10 chickens , I just started with the chickens. I had 12 eggs and got 10 to hatch so that a prettt good hatch rate.
